SPEGIFICATION forming part of LettersBatentNo. 657,117, dated September 4, 1900. Application filed October 21, 1899. Serial No. 734,337. (No model.)

To all whmn it may concern.-

Be it known that we, SIMOND JOHNSON and KELLYJ AMESON,GitiZeI1S of the United States, residing at Spanish Fork, in the county of Utah and State of Utah, have invented a new and useful School-Globe, of which the following is a specification.

Our invention relates to time or geographical globes in which means are provided for rotating a globe at a proper speed to cause it to indicate the time on any meridian of longitude and to serve as an ordinary clock, the object of the invention being to simplify and generally improve the construction and operation of such devices.

In the drawings forming part of this specification, Figure 1 is a perspective view of a device embodying our invention inclosed in its case in position for practical operation.

Fig. 2 is a top plan view with the cover of the case removed. Fig. 3 is a vertical sectional view of the same on the plane indicated by the broken line 3 3 of Fig. 2 looking in the direction indicated by the arrows. Fig. 4 is a section on the plane indicated by the broken line 4 4 of Fig. 2. Fig. 5 is a detail sectional view on the plane indicated by the broken line 5 5 of Fig. 2. Fig. 6 is a view in elevation of part of one end of the longitudinal swinging frame in which the globe is pivoted at the equator. Fig. 7 is a detail sectional view on the plane indicated by the broken line 7 7 of Fig. 2 looking to the right as indicated by the arrows. Fig. 8 is a similar view on the plane indicated by the broken line 3 8 of Fig. 2 looking downward as indicated by the arrows. Fig. 9 is a fragmentary detail view in elevation, showing part of the opposite end of the longitudinal swinging frame from that illustrated in Fig. 6. Fig. 10 is a detail sectional view on the plane indicated by the broken line 10 10 of Fig. 8. Fig. 11 is a similar view on the plane indicated by the broken line 11 11 of Fig. 7. Figs. 12 and 13 are fragmentary detail perspective views to be explained hereinafter.

Like numerals are used to indicate the same parts wherever they appear in the several ment.

outline, to which is fitted an inverted boX- like top 15, having an inclined top 16 and provided with a circular pane of glass 16, through which the globe may be inspected.

In the box or case 14 a rectangular frame 17 is swung on pivots 18 18, threaded through openingsin the sides of the box, and thereby rendered adjustable and removable.

19 indicates the globe, which is provided with lines 20, indicating parallels of latitude, and lines 21, indicating meridians of longitude, the globe being also painted or otherwise provided with the divisions of the earths surface, as usual, with terrestrial globes. The globe is in two parts, divided at the equator, one representing the northern and the other the southern hemisphere, said hemispheres being connected together by pins 22 23, inserted through plates or lugs 24 25, inserted in and projecting from their meeting edges, as best shown in Fig. 3, a pin 22 also passing through holes in the lapped ends of a chain 26, inserted in a groove formed by rabbeting the edges of the hemispheres, said chain encircling the joint on the equatorial line. The globe is frictionally secured on two tubular shafts 27 28, one of which projects at the north pole and one at the south pole, such shafts at their inner ends being bolted or otherwise rigidly secured to the plates 29 30,

which are secured together by rods 31 at the proper distances apart to form the frame for containing a coiled niotor-spring'32, the outer end of which is secured to said frame, while the inner end is secured to a solid shaft 33, which passes through the spring, the frame, and the tubular shafts projecting at the poles of the globe and pivotally mounted or journaled in the swinging longitudinal frame 17.

The outer end 34 of the solid shaft is square to receive a key for winding the spring 32, while the opposite end carries a ratchet-wheel 35, cooperating with a pawl 36, pivotally se-' cured to frame 17 and held in contact with the wheel by a spring v37 for the purpose of holding the shaft against backward move (See Fig. 9.)

On the projecting end of the tubular shaft 27 is secured a gear-wheel 38, which is the beginning of a train of clock-gearing suitably mounted on the inside of the frame 17, said clock-gearing comprising (see Fig. 5) the pin too ion 39, with which gear 38 engages on shaft 40, a gear-wheel 41 on the same shaft meshing with pinion 42 on shaft 43, a gear-wheel 44 on shaft 42 meshing with pinion 45 on shaft 46, a gear-wheel 47 on shaft 46 meshing with pinion 48 on shaft 49, an escapement-wheel 50 engaging with escapement-lever 51, balance-wheel 52, hair-spring 53, and regulator 54. A dial for hour and minute hands and a dial 56 for seconds-hand may be secured on the outside of the swinging frame 17, the shafts for the hands being extended through the frame. At the outer end of the tubular shaft 28 it passes loosely through a short tube 57, secured to the globe and carrying a gear-wheel 58, (see Fig. 3,) which gear-wheel meshes with a pinion 59, loosely mounted on a sleeve 60, formed with a gear-wheel 61, loosely mounted on a short shaft 62, mounted in the frame 17, (see Figs. 2, 8, and 10,) said pinion being mounted between a Washer 63 and a spring-washer 64, the latter being between the pinion and the gearwheel 61. The gear-wheel 61 meshes with a gear-wheel 64 on a short shaft 65, secured in frame 17, and the gear-wheel 64 with a gear-wheel 66, fixed on the tubular shaft 28.

On one end of the frame 17 is secured a plate 67, (see Fig. 13,) which is notched on its upper edge at 68 and provided with holes 69, 70, and 71, the latter being threaded to receive a screw 72, which secures a curved arm 73 to the plate, the arm being broadened at its base and provided with lugs 74 to enter holes 69 and 70, and the arm at its junction with its broadened base fitting in the notch 68. The curved arm 73 overhangs the globe and at its outer end is provided with a pivoted finger 75, adapted to extend at right angles to the arm, as in Fig. 2, and point out the name of a month on one of the two nameplates 76 77, the finger being held in this position bya spring 78, secured to the arm and having a hooked end 78 to enter a notch in the finger. The finger may be folded against the arm and will be held folded by the spring bearing against it.

The name-plates are inscribed with the abbreviated names of the months, beginning at the top with Dec, the names on one running from Dec. to Jun. in forward order and 011 the other from Dec. in reverse or backward order and are interchangeable with each other, each plate having a keeper on its rear face, as at 80 S1 in Fig. 12, to receive a dovetailed bar 82, which not only serves to hold the plates together, butby fitting in dovetail notches 83 S4 in the edges of a metal frame serves to secure the plates to said frame, which is mounted on awooden bar85, secured to the case 14 on its upper edge. By adjusting the position of the globe so that the finger will point to a specified month we are enabled to show the proper inclination of the earth during that month.

The globe is pivotally mounted in the frame 17, as before stated, to properly incline its polar axis to the horizon and is held at each inclined adjustment by a clamp-block 86, drawn against it by means of a screw 87, upon which it is swiveled (see Fig. 11) and which may be turned by a suitable key fitting its outer square end 88, the screw being threaded through a sleeve 89, set in one side of the case 14.

Around the equator of the globe are indicated the hours of the day in two series of from 1 to 12 each, and longitudinally arranged in the same vertical plane as the polar axis inside the cover and under the glass 16 is a wire 90, which will always parallel the meridians of longitude when on the upper side of the globe.

In operation the globe is rotated by the motor-spring, the clock-movement regulating its motion, so that it will make one complete revolution in twenty-fou r hours, and the time of day or night may be taken by observation through the glass with the wire as a gage or by observing the dials on frame 17. The inclination for each month is secured as described, the plates being reversed from winter to summer, and vice versa.

The gearing at the outer end of the tubir lar shaft form a frictional brake, holding the globe against slipping, but permitting of its movement by hand to regulate it.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination with a globe, of a frame within which the globe is journaled at its pole, a case in which the frame is journaled in line with the equatorial diameter of the globe, a plate on the casing having the months indicated thereon, and a pointer carried by the swinging frame and movable over said plate when the frame is moved on its equatorial journals to indicate when the globe is at the proper inclination from the horizontal for each successive month, substantially as described.

2. The combination with the casing, of the frame swung therein on equatorial journals, the globe mounted in the frame on polar journals, the month-plate secured to the casing at one of its sides in line with the journals of the frame and curved on the are of a circle having the frame-axis as a center, a 1ongitudinal arm secured to the end of the frame and longitudinally overhanging the globe, and a rigid finger or pointer projecting laterally from said arm and adapted to indicate on the month-plate when the globe-frame is swung on its equatorial journals, substantially as described.

3. The combination with the casing, of the frame swung therein on an equatorial axis, the globe swung in the frame on a polar axis or shaft, a clock mechanism outside the globe and connected up therewith to actuate the globe on its polar axis, a spring inside the globe to drive the clock mechanism, and means at the south pole of the globe to prevent backward rotation thereof, substantially as described.

4. The combination with the casing, of the frame swung therein on an equatorial axis, the globe swung in the frame on a polar axis or shaft, a clock mechanism outside the globe and connected up therewith to actuate the globe on its polar axis, a spring inside the globe to drive the clock mechanism, figures 10 arranged around the equator of the globe to indicate the hours of the day and night, a cover for the casing, a transparent pane in the top thereof, and a meridian-line thereon, immediately over the polar axis of the globe, substantially as described.
